Brushless Rock Crawler

[Xtreme R/C]

I'm thinking about building a brushless powered rock crawler.

I want to use one motor.
2 or 3 cell LiPo.
I have the gearbox and axles figured out.

I need some recomendations on a motor. I see the lehner's go up to 40 turn with a very low kv rating around 700 rpm per volt. I rely don't want to spend that kind of money on a crawler. Does Feigao have an equivilant, or a BK wanderer? I can't find the specs or a list of the availble Feigao's or BK's. Other than what Mike has or carries.

Will these low rpm motors have lots of torque?
Can I get away with a lower rated speed controller?
